Be it lrnown that I, HORACE.G. ALEXAN- DER, .a citizen of the United States, residin at Londonderry, in the county of Windhand .sive-Engines, of specification.

and State of Vermont, have invented a new and useful Cooling Attachment for Explowhich the following is a This invention relates to means for kee mg the cylinders of explosive-engines at t e proper temperature;

ilhe principal objectis to provide a simple structure in the form of an attachment that can be readily associated with any ordinary type of motor and when connected with a suitable supply of cooling medium-as, for instance, air under pressurefit will properly direct such medium against the walls of the motor, so as to effectively maintain the same at thedesired temperature.

' The referred embodiment of the inven tion is illustrated in the accompanying draw; in" s, wherein- 'gure 1 is a side elevation of a motor,

showing .the cooling attachment applied thereto and con'nectedwith a fan or b ower. Fig. 2 is a longitudinal sectional view through the attachment. Fig. 3 is a horizontalsea- 'tional view on the line3 3 of Fig. 2.

sponding parts in all the figures of the drawin the embodiment illustrated a hollow or tubular head is employed comprisin a cylihdrical side wall 4 and inner an .outer walls 5 and 6. The inner wall 5 is perfo-.

rated, as shown at 7. The outer wail 6 is detachable from the annular wall 4, the joint,

between-these walls'being preferably, though not necessarily, beveled, as shown at S. The wallets heldin place by suitable tiebolts 9,

assing through and engaging the inner peribrate'd Wall 5. Projecting'frorn the marginal portion of the inner wall 5 are spaced parallel pipes 10, communicating With the interior of the head and having openings 1 1 in for instance, in Fig. 1, the pi cs 10' extend.- ing alon side the cylinder and emg arrange-d around tr e same. Air or other suitable coolmg medium is conducted to the head through I Specification of Letters Patent.

Likenumerals of reference designate corre Patented Sept. 11, 1906.,

a suitable conduit 13 from any source-as, for instance, a blower 14. It will thus be apparent that the cooling medium sup lied t rou h the'conduit 13 will enter the ead andtie pipes 10. discharged through the orifices 7 and 11 against the cylinder-head and the side walls thereof, so as to cool the cylinder. At the same time the structure is entirely separate Consequently it will .be'

from the engine and can be removed at any time if it is found desirable or expedient to do so. Moreover, theattachment may be manufactured separately from the engines and, applied to substantially anyt e, whether vertical or horizontal. In case t e motors are provided with i nition-plugs in their rear ends the inner wall 5 is provided with an opening 15 to receive the projecting portion of said plug, and by this arrange: ment it is then only necessary outer wall 6 in order' to gain access to the P s be apparent to thoseskilled in the'art without further description, and it will be understood that various changes in the size, shape,

proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. I

,Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is Y 1. A cooling attachment for explosive-en- '75 to remove the.

From the foregoing it is thoughtlthat the construction, operation, and many advan-- tages of the herein-described invention will gines', comprising a hollow head arranged to- I e placed contiguous to the cylinder-head of an explosive-motor, and spaced pipes carried by the head and arranged to surround such cylinder, said pipes being separate from the' their inner sides.

2. A cooling attachment for explos1ve-encylinder and having perforations through g nes, comprising a hollow head arranged to be placed contiguous to the cylinder-head of an explosive-motor and having an inner perforated wall, and spaced pipes carried by the head and arranged to surround such cylinder, said pipes having perforations through their inner side walls. I

3. A cooling attachment for explosive-enmes, comprising a hollow head arranged to be placed contiguous to the cylinder-headof an explosivemotor and provided w1th an m- IIO let for the cooling mediunr saidhead having an inner erforated Wall and an outer relnovmy own I have hereto al'lixed Iny signature in able Wal means for securing the outer wall l the presence of two wltnesses.

in place, and spaced pipes rojeotim from v r Y the margins of the innerwal and ari anged HORACE ALEMNDER' 5 to surround the cylinder, said pipes having Witnesses:

perforations through their inner side Walls. E ADDISON E. OUDWORTH,
